Is this truly a blocker for 1.4? I would actually downgrade it to major. If we get it in for 1.4 then it's great, if not then we'll include in the next release.

> Currently, if Flink cannot complete a checkpoint, it results in a failure and recovery.
> To make the impact of less stable storage infrastructure on the performance of Flink less severe, Flink should be able to tolerate a certain number of failed checkpoints and simply keep executing.
> This should be controllable via a parameter, for example:
> {code}
> env.getCheckpointConfig().setAllowedFailedCheckpoints(3);
> {code}
> A value of {{-1}} could indicate an infinite number of checkpoint failures tolerated by Flink.
> The default value should still be {{0}}, to keep compatibility with the existing behavior.
